The Senate Homeland Security and Governmental Affairs Committee will hold the first congressional hearing on the Secret Service prostitution scandal later this month, its chairman said Sunday on CNN's "State of the Union."

Sen. Joe Lieberman (I-Conn.) said his committee will hold a hearing on May 23 with Secret Service director Mark Sullivan and Charles Edwards, the acting inspector general of the Department of Homeland Security. And Lieberman said he has at least three lines of questioning:

"Is the inspector general satisfied with the investigation of what happened in Cartagena that the Secret Service did?"

"Were there indications before the Colombian scandal of behavior of Secret Service agents - off duty, on assignment - that should have been a warning that this was coming?"

"What are you going to do, Director Sullivan, to make sure that nothing like this ever happens again?"
